Question | Answer |
Skeletal Cartilage | made up of some variety of cartilage tissue, which consists primarily of water |
cartilage tissue | consists mostly of water, accounting for its resilience, that is the ability to spring back to its original shape after being compressed |
perichondrium | The cartilage which contains no nerves, or blood vessels, is surrounded by a layer of dense irregular connective tissue, the ________ |
perichondrium | "around the cartilage" acts like a girdle to resist outward expansion when the cartilage is compressed. Contains the blood vessels from which nutrients diffuse through the matrix to reach the cartilage cells. |
three types of cartilage tissues: | Hyaline cartilages, elastic cartilages, fibrocartilages |
chondrocytes | basic components of cartilage tissues |
chondrocytes | encased in small cavities (lacunea) within an extracellular matrix containing a jelly like substance and fibers |
Hyaline Cartilages | look like frosted glass when freshly exposed, provides support within flexability and resilience. |
Hyaline Cartilages | Most abundant skeletal cartilages |
Skeletal Hyaline Cartilages include | articular cartilages, costal cartilages, respiratory cartilages, nasal cartilages |
articular cartilages | covers the ends of most bones and movable joints |
costal cartilages | connect the ribs to the sternum (breastbone) |
respiratory cartilages | form the skeleton of the larynx (voicebox) and reinforce other respiratory passages |
nasal cartilages | support the external nose |
Elastic Cartilages | looks very much like hyaline cartilages, but they contain more stretchy elastic fibers and are better to stand up to handle repeated bending. |
Elastic Cartilages | type of cartilage in the external ear and the epiglottis (the flap that bends to open the larynx each time we swallow |
Fibrocartilage | highly compressable and have great tensile strength |
Fibrocartilage | The perfect intermediate between hyaline and elastic cartilages, ________ consist of rughly parrallel rows of condrocytes aternating with thick collagen fibers. |
Fibrocartilage | occur in that are subjected to both heavy pressure and stretch, such as pad like cartilages (menisci) of the knee and the discs between the vertibrae |
